This has been going on for near a month now.
It's at it's worst during primetime. I've done a few tests late on a Saturday (3am, etc) and the speed is back up around 85+ Mb/s- I can't be fully certain since I'm not always at home using the Internet outside of primetime so I can't be sure of the consistency but it sure seems that way. It's so bad now that we can no longer stream HD Netflix, nevermind the 4K Netflix/Amazon Prime we used to enjoy. Until this point, our connection has been damn near flawless for a year since installation. I've got a topic opened on OptimumDirect with no solution yet (It's been weeks).
Here's my current stats from the Arris TM822G:
